To the Editors of the Annals and Magazine of Natural History.
Gentlemen,
You would greatly oblige me by giving, as soon as possible, a place in your most valuable Journal to the enclosed paper, containing the diagnoses of new or little-known annelids collected in the 'Porcupine' expedition, and lately examined by me.
I am, Gentlemen,
Yours truly,
E. Ehlers, M.D., P.P.O.
